Subject: Re: [SG10] Feature Test Macro for destroying operator delete?

We'll presumably need both a language component and a library component,
but user code will only want to test one macro.
Perhaps the compiler should define a macro for language support and the
library should only define its macro if the compiler macro is defined (as
min(compiler macro value, library value)?).
